Overall, very nice samples, and great quality in the sound mix. Reminds me of David Wise (DKC composer). I personally feel the song takes a bit too long to get started, as it was too blank for too long for my tastes. Once it gets going it's great stuff. Sometimes it's better to go shorter than to stretch out to get a longer time on your song. I feel a few other times the action drops a bit too much. I do get that this is an ambient track. And for the record, what I am saying is only minor stuff.
Great song, wonderful atmosphere. Just a little drawn out at times (especially the intro/outro).
